ACME Thread Gages

                  

A C M E Thread gages is used to measure screw thread pitch. There are three gauges used- the uppermost gauge, the center, and the lower for Whitworth screws. Thread Pitch Gauge is used to determine pitch, that is on a screw. It allows the user to determine the thread and categorize the shape.

You can use a standard cutter, which is 60 degrees. Once you have made the proper adjustments, you can grind at an angle of 4 degrees. You would then move up to an angle of 14.5 degrees, by holding the HSS lower belt. You will then need to check the gauge to make sure there are not gaps between the thread and the gauge. If there are no gaps, you will need to make corrections.

You will also need to spread some time, grinding for optimum results. You must also remember to no allow the process to overheat. The next step is to put a 0.5 inch to face the end to provide tailstock. You can then start normal threading and choose the length of the A C M E Thread rod and make the proper threading. You will repeat the process, to get positive results.

ACME thread gages also used for translation motion in machine tools. The specifications are ASME B15-1997, thread plugs, rings, check plugs, and TPI from 16 to 2. The popular Unified Thread Gauge is used for the purpose of measuring the lead or pitch of a screw. The Metric Thread Gauge is used to measure the sizes of the wrenches, nut and bolts, the NPT Gauge provide range, the Recoil Thread is used for checking tapping, Iso Metric Thread Gauge resist corrosion and PG Thread Plug Gauges are used for checking thread of pipe fittings.
